Description
Technical field
The present invention relates to a kind of construction of reinforcement, particularly a kind of job practices of silicon rubber strengthened with GFRP sheets beam.
Background technology
Engineers and technicians often can run into the engineering that beam needs reinforcement, and the reason that beam goes wrong is more complicated, have the many reasons such as design, construction, material factor single or mix.Common are: there is through crack in beam; Beam deflection is excessive; Concrete class or the area of reinforcement do not reach requirement etc.Traditional beam reinforcement means is to utilize steel that beam is reinforced, and in order to improve consolidation effect, steel is applied the globality that prestressing force is strengthened ruggedized construction.Because steel product cost is higher, silicon rubber glass fabric material intensity is higher and cost is lower, the present invention utilizes silicon rubber glass fabric material to apply prestressing force, applies very large not the differing greatly with the wood property and the steel that are exactly the silicon rubber glass fabric of prestressing force with utilizing steel.Silicon rubber glass fabric material is comprised of the monfil that does not have each other bonding, lack bonding so that between the fiber stress distribution very inhomogeneous, and lack ductility i.e. fracture after the intensity so that the silicon rubber glass fabric of monofilament reaches capacity.Therefore the silicon rubber glass fiber cloth silk of high stress areas can rupture before the complete Developed fiber strength of silicon rubber glass fiber cloth silk of low stress zones, all silicon rubber glass fiber cloth silks are Developed fiber strength simultaneously, the bulk strength of material will be well below monfil, and the pair cross-section stress distribution is inhomogeneous very responsive.Therefore a key issue in the technique is exactly how to make the internal force distribution in cross section when stretch-draw of silicon rubber glass fabric even as far as possible, thereby the silicon rubber glass fabric can be stretched to higher stress level.
Summary of the invention
Technical problem to be solved by this invention provides a kind of job practices of safe and reliable silicon rubber strengthened with GFRP sheets beam.
Facility are the principles that adopts the frictional force self-locking to the anchoring of silicon rubber glass fabric among the present invention.Anchor device is comprised of two semicylinders, and one of them is fixed on the facility, and another one is closely pressed together on it by bolt.During use with the end clips of silicon rubber glass fabric between two semicylinders of anchor device, with bolt with the semicylinder pressing, then rotate above anchor device is wrapped in the silicon rubber glass fabric, volume to the length of 8 times of anchor device diameters namely provides the enough frictional force that is produced by self-locking.The anchor device diameter is 6cm, can guarantee can not produce large deformation when bearing the pulling force of 5t therefore have enough large rigidity.
Turning handle after silicon rubber glass fabric two ends all being fixed on the anchor device of two facility drives the bolt rotary of main frame tool.Because the anchor device of main frame tool is to be enclosed within on screw rod and the slide bar, bolt rotary must make anchor device move along screw rod and slide bar, thus tensioning or loosen the silicon rubber glass fabric.The stroke of whole screw rod has 50cm long, can satisfy the deformation requirements that the long silicon rubber glass fabric of 25m is carried out stretch-draw, thereby the long-span beams member is carried out effective prestressed reinforcement.Be fixed on the post member during facility construction, because the direction of screw rod is the parallel columns member, so that the stretch-draw direction also is parallel columns member and vertical beam member, must adopt the transfer of facility, the direction that a roller bearing by the facility top changes the silicon rubber glass fabric makes it be parallel to beam.Because roller bearing is positioned at the top of facility, the silicon rubber glass fabric change after the direction can milli unhinderedly with beam bottom close contact, thereby guarantee sticking Quality.
Through long experimental study, discovery is by making the silicon rubber glass fabric in silicon rubber glass fabric reinforced plastic, directionality and the planeness of two anchored end of control silicon rubber glass fabric reinforced plastic, control three committed steps of suitable tensioning speed, the stretch-draw of silicon rubber glass fabric can be reached higher stress distribution.Another one key issue in the technique is because the silicon rubber glass fabric after the stretch-draw is very straight, therefore the reinforced surface of flexural member to be reinforced must be also very straight, bond quality guarantee is between the two namely reinforced the more common non-prestressed reinforcing technique of requirement of surface finish of flexural member to need higher.
